摘要
本文合成了聚(环氧乙烷-环氧丙烷-烯丙基缩水甘油醚,三元共聚物,P(EO-PO-AGE)。扭辨分析、DSC、X-射线衍射结果表明,三元共聚物的玻璃化转变温度较低(T_g=-74℃),无定形结构含量~98%,并确定了与LiClO_4组成为Li/O(mole)=0.25的结晶络合物存在。络合物电导行为的研究发现,络合物电导与盐浓度有关,在Li/O(mole)=0.05时具有较大值,室温下电导可达5×10^-5)scm^(-1)。
A amorphous ternary polymer, Poly (ethylene oxide-propylene oxide-allyl glycidyl ether) was prepared, and it shows a low glass transition temperature (Tg=-74℃) and a high amorphous ratio (98%). DSC and X-ray diffraction measurements were employed to characterize the P(EO-PO-AGE)-LiClO4 complex morphology, a crystall complex with the composition of Li/O=0.25 was detected. The studies on ionic conductivities of complexes found that the conductivities change with the salt concentration, and reached a maximum of 5×10-5scm-1 at room temperature with Li/O = 0.05.
